The following character string is to be transmitted using Huffman coding:
Describe the Huffman code table.
Network Noise and
Noise is one of the most important factors affecting the operations of
IC circuits. This is because noise represents the smallest signal the
circuit can process.
The principle noise s
Modulators and Demodulators
Modulation is the modification of a high-frequency carrier signal to
include the information present in a relatively low frequency signal. This
is necessary because radio wave propagation is more efficient at highe
Instabilities, Oscillations and Oscillators
If positive feedback is applied to an amplifier, the feedback signal is in
phase with the input, a regenerative situation exists.
If the magnitude of the feedback is large enough, an unst

Introduction to Radio Communication System
A radio communication system involves in the t
Most amplifiers in communication circuits are small signal amplifiers.
Hence, they can be described by linear equations. We will consider
several amplifiers including BJT, FET, operational amplifiers and
Sensors and Detectors
A detector is typically the first stage of a communication system. Noise
in this stage may have significant effects on the operation of the entire
system. In this chapter we will use detector and sensor interchangeably.
Noise in BJT
The objective is to determine Eni , En and I n for a bipolar transistor.
The hybrid- model that includes the noise sources is shown below
The feedback elements C and r are removed . This is OK for
frequency < 1T/ 2 . At frequencies
CAD For Noise Analysis
SPICE contains built-in models for passive elements, semiconductor
devices etc. by including control lines in an input file, SPICE can
be made to perform various analyses of a circuit including noise
